ELLET SANBORN, OF PORTLAND, MAINE, ASSIGNOR 0F ONE-HALF TO DONALD J.MACDONALD, OF PORTLAND, MAINE.

COMBINED BOW REST AND LOCK.

To all whom it may concern:

Be it known that I, ELLET SANBORN, a citizen of the United States,residing at Portland, in the county of Cumberland and State of Maine,have invented certain new and useful Improvements in Combined Bow Restsand Locks, of which the following is a specification.

This invention relates to a combined bow rest and lock. It is designedto provide the bows constituting a part of the tops of automobiles andother vehicles with a combined rest and lock which will serve tomaintain the bows against accidental lateral or vertical movementrelative to each other'and which will be convenient to operate.

In the drawings herewith accompanying and making a part of thisapplication, Figure 1 is a side elevation of a set of bows showing myimproved combined rest and lock applied thereto; Fig. 2 is a plan viewof the meeting face of one of the members; Fig. 3 is a plan view of themeeting face of the complemental member; Fig. 4: is a longitudinalvertical section partly in elevation of the two complemental members inposition; Figs. 5 and 6 are plan views of the meeting faces ofcomplemental members of a different embodiment of my invention; Fig. 7is an elevation of the modification shown in Figs. 5 and 6; Fig. 8 is anelevation of a port-ion of the bow supporting bracket and a speciallocking member supported thereon; and Fig. 9 is a transverse sectionalview of one of the locking members shown in Fig. 2, designed especiallyto show a means of holding a locking device out of position.

Same reference characters indlcate like parts in the several figures.

In said drawings, A represents the bows in the top of a vehicle and B isa bracket secured to the body of the vehicle which supports the bows asa whole when turned back. Upon this bracket is an upwardly projectingtongue piece 0 adapted to be secured to bracket B in any convenientmanner, as by a set screw D, and provided with an upwardly projectingtongue E having a transverse lock receiving hole F. Attached to theupper side of eachbow is a tongue piece C similar to that shown in Fig.8 except as to the manner in which it is sup ported. Where it isattached to a bow it has downwardly curved flanges Gr adaptedSpecification of Letters Patent.

to extend down over the sides of the bow and to be secured to the bow inany convenient manner as by screws H. These members are provided withupwardly pro ecting tongues E similar to that shown in Fig. 8. To theupper side of each bow is secured complemental tongue receiving membersI provided with tongue receiving sockets J adapted to give entrance tothe upwardly projecting tongues of the members C, and these members areprovided with similar flanges K and are secured to the bows in anyconvenient manner, as by screws L. The sides of the socket are providedwith holes M adapted to register with the hole F in the tongue piecewhen the tongue is in the socket. It also has another hole N. The lockconsists of a U-shaped bar, one arm 0 being longer than the other arm P.The arm P is adapted to pass through the holes M in the member I andthrough the hole in the tongue, and the long arm to pass through thehole N in the member I. The long arm is provided with an operating leverQ, preferably in the form of an enlarged head. Between said head and theside of member I is inserted a tension spring R adapted normally to holdthe looking member in engagement but yielding, when force is applied, topermit the short arm of the locking bar to be withdrawn from the tongue,thus permitting the members to separate and the bows to be raised. Whenthe short arm is entirely withdrawn the long arm may be turned partlyaround bringing the short arm out of register with the holes, and thuspreventing its return to locking position when force is removed from thelong arm. A convenient arrangement for holding the locking arm ininoperative position is to form a groove in the outside of the wallforming the socket adjacent to the hole M into which the end of theshort arm passes when the locking bar is rotated, as shown at S, Fig. 9.The member C at the base of the tongue may be countersunk, as shown atT, and the walls forming the sockets in members I may be curveddownwardly, as seen at U, whereby the members are held more firmly inlooking position.

In Figs. 5, 6 and 7 I have shown a modified structure involving howeverthe same fundamental principles as thoseshown in Figs. 2 and 3. In thiscase the member I is provided with a downwardly extending offset V andthe member C is provided with an upwardly projecting oflset IV on theopposite side thereof. The long arm of the looking bar passes throughthe body of the memher I and the short arm returns through the offset Vin member I and into the oiiset W in member C when in locking position.For convenience and strength the member I is provided with a tongue Xadapted to take into a tongue receiving socket Y in the member C. Inthis case a convenient method of holding the locking bar in inoperativeposition consists of a spring bar Z in the path of the head 0 of thelocking bar, so that when the locking bar is moved into inoperativeposition the head passes over the inclined side of the offset Z and isheld thereby in inoperative position until manually released by pressureon the free end of the spring.

The manner of arranging the interlocking parts and the locking devicemay be varied and still be within the spirit and scope of my invention,provided only that the complemental members are capable of being lockedtogether and are capable of being manually moved into and temporarilymaintained in inoperative position while the bows are being raised. Thisis important to enable the bows to be raised by one person, thisconstruction enabling the parts to be unlocked ready to receive the bowswhen it is desired to drop the top, the locking members being thereby inready position.

The operation of my improved device is evident from the drawing anddescription,

and it will be evident that the members may be reversed if desired.

I claim:

1. In a combined bow rest and lock, two members, one provided with asocket and the other with a tongue adapted to take into said socket, anda hook-shaped locking bar having a short arm adapted to pass through thewalls forming the socket and through the tongue and a long arm slidablymounted in the body of the member.

2. In a combined bow rest and lock, two members, one provided with asocket and the other with a tongue adapted to take into said socket, anda hookshaped locking bar having a short arm adapted to pass through theWalls forming the socket and through the tongue and a long arm slidablyand rotatably mounted in the body of one of the members.

3. In a combined bow rest and lock, two members, one provided with asocket and the other with a tongue adapted to take into said socket, ahook-shaped locking bar having a short arm adapted to pass through thewalls forming the socket and through the tongue and a long arm slidablymounted in the body of the member, a hand hold on the end of the longarm and a spring interposed between said hand hold and the socketmember.
